The following components will be included in the Electrical Harmonic Analysis and Survey:
Power Network System Measurements and Data CollectionPower network system measurements and data collection are typically taken at various essential locations throughout the facility to enable the accurate modelling of harmonic sources. This is required since the theoretical addition of harmonics from a number of sources will not be directly additive and could be considerably less. In addition to harmonic measurements, voltage and load measurements are also taken.
- System Voltage RMS
- System Current RMS
- Active & Reactive Power
- Power Factor (Instantaneous).
The job shall also further include the following
- Data collection from site.
- Harmonic measurements along with specific harmonic filtering at normal operating conditions.
- Voltage Improvement & stability study.
- Three phase balancing study.
- Surge & Transient Protection, study.
- KVA Capacity Release
- Broadband Harmonic reduction requirement if any.
Harmonic Analysis
A harmonic analysis involves the use of computer programs to identify and predict potential harmonic problems and mitigation techniques. The study will also look at different operating points as well as system. Changes that might occur in the future.
Surges & Transient Analysis
The study will be conducted to record the transient s & surges of 1KV – 6KV magnitude.
Voltage Dips Swells Analysis
The study will be conducted to record the short term dips & swells along with magnitude & duration.
Reactive Power Analysis
The study will be conducted to calculate the desired reactive power at distribution & load end. This will give precise reactive power & maintain unity power factor at PCC & reduce losses & resonance in network.
Captive Power Analysis
The study will be conducted to calculate the desired captive power.Synchronise the captive power to cater to peak demands & reduce utility surcharge& fuel consumption.
Load Flow Analysis
The study will be conducted to calculate the desired captive power.Synchronise the captive power to cater to peak demands & reduce utility surcharge& fuel consumption.
A load flow analysis is conducted to predict power flow magnitudes, power factor, voltage levels, and losses in branches of the system based on the specified operating conditions. The job for the Electrical system Power Quality study and analysis shall be carried out as indicated below:-
